Brand New - Okay I Believe You, But My Tommy Gun Don't Lyrics Meaning

I know, its a stretch, but this song is about a breakup..and not with a girl. Its about Adam from taking back sunday. The phrase where he says “ And these are the words you wish you wrote down
This is the way you wish your voice sounds” who else sings and wrote songs??? Adam. In many of his songs Eddie doesnt use pronouns for a female so its in the air who he’s talking about. But in another phrase he says “ Every line is about who I don't want to write about anymore” the more you listen to the songs you see how much connections he makes with Taking Back Sunday. I have much more interpretations but thats it for now !
